Abo, a fourteenth-century pueblo ruin in central New Mexico, was once a Tompiro-speaking community and major trading center linking the Rio Grande pueblos, Plains peoples, and nearby Salinas salt deposits. In a high, dry farming landscape, its residents relied on agriculture, hunting, and gathered foods while exchanging salt, bison products, and other goods. Spanish contact likely came in 1583 with Antonio de Espejo, and Franciscan missionary work began in 1622, followed by church construction in 1629. Recorded with more than 1,600 inhabitants in 1641, Abo was abandoned around 1672, apparently because of drought and Apache attacks, making it a key surviving site for understanding Tompiro life, trade, and Spanish missionization.
